'| M PROVEM ENT IN WATER-HEATERS.

Specification forming part of Letters Patent No. 201,885, dated April 2,1878;

application filed July 21, 1877.

a new and useful Improvement in Water- Heaters, of which the followingis a full description, reference being had to the accompanyin gdrawings, in which Figure 1 is an elevation; Fig. 2, a bottom view withour attachment; Fig. 3, a top view of the same 5 Fig. 4., a verticalsection thereof.

It is customary to heat water in a reservoir by means of pipes passingthrough the firechamber of a stove or range. It frequently happens,especially in warm weather, that it is not desirable to maintain afirein the stove or range, in which case hot water cannot be provided in thereservoir.

The object of this invention is to provide devices by the use of whichthe water in the reservoir can be conveniently heated without the use ofa stove, or which may be used in connection with the stove, if desired,for a more rapid heating-of the wafer; and it consists in an attachmentconnected with the water-pipes between the reservoir and stove, throughwhich the water circulates, and to which the heat from a coal-oil stovecan be easily applied, for the purpose of heating the water.

In the drawings, A represents a water-res. ervoir, of the usualconstruction, arranged and supported in the usual manner.

B is a stove 'or range; 0, the water-pipes passingfrom the bottom of thereservoir A through the stove B D, the return-pipe to the reservoir.These pipes are arranged in the usual manner, except that their locationmay be changed, as may be necessary to adapt them to be used inconnection with our attachment.

E represents our attachment. It is connected with and suspended from thepipe D near the reservoir by means of a T-connection. It is alsoconnected with the pipe 0 near its lower end-.-for example, at a-so thatwater from the reservoir can pass into and cir-. culate through thisattachment to facilitate the heating. The attachment is provided with aseries of tubes, 0, open at the top and bottom thereof, which tubes weprefer to make smaller at the top than at the bottom, and to place in adiagonal position, rather than to have them extend perpendicularlythrough the attachment. I Through these tubes the heat passes, and thewater in the attachment surrounds them. We prefer to make the bottom ofthe attachment concave, as shown at d,

Fig. 4. eis a sliding band encircling the attachment. F is a jacket overthe same, arranged so that there is a space between it and the at- I Inuse, the water in the reservoir A can be V heated by means of thecoal-oil stove G, the heat from which first strikes the plate d of theattachment, and then passes up through the tubes 0. The greater portionof the heat will be absorbed by the water in the attachment, andaportion of that which escapes at the top Willbe utilized by means ofthe jacket F.

When the stove G is in operation the water in the reservoir willcirculate through the at tachment E, passing from the pipe 0 into E ata, and thence'out into the pipe D at b, and thence into the reservoir.

The stove G is not necessarily a fixture beneath the attachment E, butmay be removed and used as in the ordinary manner, being placed beneaththe attachment when not in use for other purposes; ora coal-oil stovemight be permanently located beneath E, if desired.

The chief purpose of the attachment is to provide means for heatingwater in the reservoir when there is no fire in the stove or range B;but the attachment may be used in connection with the stove, if desired,one not interfering at all with the operation of the other.

The band 6 extends a little way below the lower end of the attachment E,and it may be lifted up to allow the stove G to be placed beneath theattachment, and when in place the band 0 can be let down again, thusaiding t0 confine the heat.

This device has been found efficient in prac- 2. The Water-heatingattachment and pipes a b, in combination with the circulating-pipes G D,substantially as described.

3. The water-heating attachment E, in combination with the air-jacket F,to hold the hot 7 air and prevent circulation around the heater E,substantially as specified. l

4.. The suspended heater E, in combination with the removable stove orlamp G and circulating-pipes O D, substantially as described.

5: The movable band 6, in combination with the suspended heater E andremovable oilstove or lamp G, substantially as and for the purpose setforth.
